如何为 php 配置 bootstrap
我只是尝试从 php 和 bootstrap 开始，但由于某种原因我的网站无法识别 bootstrap。它不使用它的设计，而是使用简单的 html。这就是我的 index.php 看起来像：
<!DOCTYPE html>
<html lang="en">
<head>
<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.2.0-beta1/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-0evHe/X+R7YkIZDRvuzKMRqM+OrBnVFBL6DOitfPri4tjfHxaWutUpFmBp4vmVor" crossorigin="anonymous">
<title></title>
</head>
<body>
<script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.11.5/dist/umd/popper.min.js" integrity="sha384-Xe+8cL9oJa6tN/veChSP7q+mnSPaj5Bcu9mPX5F5xIGE0DVittaqT5lorf0EI7Vk" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.2.0-beta1/dist/js/bootstrap.min.js" integrity="sha384-kjU+l4N0Yf4ZOJErLsIcvOU2qSb74wXpOhqTvwVx3OElZRweTnQ6d31fXEoRD1Jy" crossorigin="anonymous"></script>
</body>
</html>
这就是我想要用作组件的页面的外观：
<form role="form" method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<div class="form-group row">
<label for="inputEmail" class="col-sm-2 col-form-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail" name="email" placeholder="Email">
</div>
</div>
<div class="form-group row">
<label for="inputUser" class="col-sm-2 col-form-label">User Name</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="inputUser" name="user" placeholder="Username">
</div>
</div>
<div class="form-group row">
<label for="inputPassword3" class="col-sm-2 col-form-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword" name="password" placeholder="Password">
</div>
</div>
<div class="form-group row">
<div class="offset-sm-2 col-sm-10">
<input type="submit" value="Sign in" name="submit" class="btn btn-
primary"/>
</div>
</div>
</form>
有人可以看看我的错误并告诉我出了什么问题吗？
